Once a great and beautiful cross-roads of Moria, the Grand Stair is a vile haven of many of the gathered tribes of Orcs. Igash, regarded as a leader by all of the varied groups, gathers tribute from every tribe to give to Mazog, the mightiest and greatest of Orcs in Khazad-dûm. The dwarves wish to unseat Igash's Orcs from this Grand Stair and stop Mazog from receiving valuable and unsavoury gifts.
'So you are the mighty ${CLASS} of whom everyone has spoken so well! Word of your valour and courage has reached my ears, but seeing as I am a disbelieving sort, I would like to see if you are made for the sort of challenge I have to offer you.
'If you are truly all that they say you are, I have a challenge for you: Igash must be defeated upon his throne in the Grand Stair, and I want to see evidence of your actions! I would have you defeat him in battle and return here with his lash so that I can see what you have done.
'This will not be an easy task, nor is it impossible. Prove yourself in this challenge of mine, and you will receive a rich reward. Oh, and... there is no shame in bringing friends with you on this venture.'
Igash can be found atop the Grand Stair, south-east of the Twenty-first Hall where Eilífr holds his post.
Eilífr has asked you to defeat Igash and collect his lash to assist in efforts to reclaim that cross-roads for the dwarves. He wishes to see the lash as proof of your deed.
